WTF - Xara mm Units

[sadicus]

What combination of settings does it take to get Xara Units to work in Win 7?

Xara Units = mm
Page Size: 100.000 x 100.0000
result: 99.9999mm x 99.9999mm (no matter the Decimal setting in Win7, the result is never 100.00mm)

Example Image
Xara exported SVG 50x50mm
Import 123D 141.733 x 141.733mm


Tried:
Win7 Program Files> Regional> Advanced> Decimal = 3
Win7 Program Files> Regional> Advanced> Decimal = 4
Win7 Program Files> Regional> Advanced> Decimal = 6

Might be the receiving application or a combination of both.

If I export two rectangles, one at 100 mm and one at 50 mm and open that file in InkScape, the results are:

Exported at 100 mm = 100.001 mm
Exported at 50 mm = 50 mm

And likely there is still a rounding (error) value past the 4 digits I use in Windows 8. InkScape only goes to 3 decimals.

Open your 50 x 50 mm object in InkScape and see if the amount of deviation is as great as 123D demonstrates.
